polynomial_templates

grizli.utils.polynomial_templates(wave, ref_wave=10000.0, order=0, line=False)

Generate polynomial templates based on the input parameters.

If line is True, the method generates line templates by applying a sign to the polynomial. Otherwise, it generates polynomial templates by raising the wavelength ratio to the power of the polynomial order.

Each template is stored in the returned dictionary with a key in the format “poly {i}”, where i is the polynomial order.

Parameters

wavearray-like

The wavelength array.

ref_wavefloat, optional

The reference wavelength. Default is 1.0e4.

orderint, optional

The order of the polynomial. Default is 0.

linebool, optional

Whether to generate line templates. Default is False.

Returns

temp: OrderedDict

A dictionary of SpectrumTemplate objects representing the polynomial templates.
